POLISHING DEVICE.

Application filed .Tune 11, 1925. Serial No. 36,537.

To all whom it may concern Be it known that I, EUSTAGE CARL'lLL BiunnnnrBritish sub ect residin at Vale 1' 1 7 Y) T ,1 Lodge, ll eston l ark,llatn, Eaomersetslnre,

lilngland, have invented a new and Improved Polishing Device, of whichthe following is a specihcation.

This invention comprises a new or im" causes considerable friction andthe nails be come heated even though a comparatively smallpressure isapplied to the pad. Moreover, whether applied to manicure purposes orother purposes the pads as hitherto constructed have not sul'licientresilienty to perform the cleansingor polishing purpose cllectually orfor any length of time Without the application of considerable pressure,as, after use for a short period, the pads become hard and hence Wantingin eiiiciency.

A feature of the present invention consists in the provision of apolishing device which incorporates an inflatable pad menr her and meansfor inflating; said pad as and when desired.

Another feature of the luv tion consists in a polishin'gdevicecomprising a pneumatic cushion having; assembled over some a cover WhichCOllSbrbllllGS or provided with a Working or polishing surface, saidcushion having incorporated therewith a pump for the inflation thereof,and the Whole being mounted in a self-contained manner upon r Within asuitable stock or holder.

A further feature resi es in the provision in conjunction with the pumpof a valve adapted to be operated. for releasing the air from thecushion when desired.

Further features of the invention hereinafter more fully described.

For the purpose of more fully describing; the nature of this invention,reference will now be made to the accompanying drawings, wherein Fig. lis a perspective view of a polishing device constructed in accordancewith the present invention.

in be f the device.

Fig. 2 is a longitudinal section through Fig. 3

is a cross section through the device.

In one convenient method of carrying out the invention, same Will bedescribed as applied to a manicure polishing pad. A StOClA or holder 1of metal, wood or other suitable rigid material is in the nature of aplate, preferably ofelliptical'shape in plan having its edges overturnedas at 1 so as to form said stock to inverted channel shape iii-plan. Thestock 1 is formed at its two ends with downwardly projecting lugs 1", 1,one of said lugs 1 having a plain hole While the other 1 has ascrew-threaded hole for the reception of a screw 2; I Assembledlengthwise beneath the stock '1 1s an air pump or inflator 3 of thecustomary single-acting type, said pump being fired in position at oneend by inserting a re duced boss portion l of a plug-or cap 4: fixed atthe one end of the pump barrellinto the plain hole in the lug 1 and atthe-other end by screwing up the screw 2. The pump rod 5 which isadapted to be reciprocated Within the pump barrel 3 carries out its inorend a suitable piston and at its outer end a knob or handle, said knobprojecting on theouter side oi: the lug- 1.

Near the end of the pump barrel opposite to that at Which the piston rodprojects a small port or perforation 6 through which an:- 1s pumped intoa. pneumatic cushion 7 i for the purpose of inflating" same. Thiscushion is preierably ct suitable elastic material and conveniently ofapp-ionimatel cigar shape, and is suitably secured attits ends tothepump in such a nianner that'the iun'ip passes through same.

Surrounding the cushion in a readily detachable anti interchangeablemanner is an outer cover 8 of Wash leather or other suitable materialwhich provides the polishing or Working surface of the pad, said coverbeing secured by adhesive or otherwise to, or having assembled therein,a rigid plate 8 of elliptical shape, which is adapted to fit within theside flanges 1 of the stock 1 so-as to retain the cover 8 in therequired position. The cover 8 is tapered at its ends so as to causesame to conform to boat shape when the cushion is inflated therein.

The port 6 in the pump barrel is covered with a piece of rubber-tubingwhich functions in the manner Well known to prevent lill') return of airfrom the cushion t0 the pump. A portion of the length of the pump barrelat the handle end may advantageously be slightly enlarged in diameter asat 10 to ensure free inflow of air to the front of the piston.

In order to permit ofthe ready deflation of the cushion a plug-likeextension 11 is secured at the closed end of pump barrel, said extensionhaving an L shaped air passage 12 therein, one arm of which passageopens out at the circumferential face of the plug while the otherextends axially to an annular chamber or recess 13in the plug amount ofmovement in an axial direction.

lVhen the sci-en 2 is tightened'up, the valve let is pressed on to itsseating and closes the passage 12, and in order to deliate the cushionall that is necessary is to unscrew the screw 2 to a small degree whenthe air will pass from the cushion by Way or the passage 12 and out fromthe end of the plug 11 past the valve let.

The stock. l'may have a handle portion 15 screwed or otherwise securedthereto, or said handle may be an integral port-ion of the stock.

I claim I v J 1. A polishing device embodying an inflatable pad and apump for inflating the same arranged Within the pad substantially asdescribed so as to produce a single, selfcontained, unit.

2. A polishing d vice embodying a rigid holder, an inflatable pad and apump, the pump being Within the pad so as to constitute therewith asingle self-contained unit, and the pump being supported in'th-e holder,thereby unitingthe pad thereto.

8. A polishing device comprising in combination a rigid holderconstructed for convenient manipulation, an inflatable pad, a pump forinflating the pad arranged to con stitute therewith a single unit, thepump being supported by the holder and uniting the pad thereto, and acover for the pad its 0 )osite endsto the holder. the mini having a.handle by which it may be Worked that is treely movable independently ofthe supporting connections for the pump.

6. In a polishing device, the combination 01 a holder having aperipheral flange, an inflatable pad adapted lobe suppor'ed be low theholder and within the confines of the said flange, a pump for inflatingthe holder having supports at its opposite e'nds in the flange of theholder, the pump having a handle by which it is operated extend ingthrough the flange, a valve controlling an exit through which the padmay be deflated, the valve having operating means extending through theflange of the holder, and an elastic cover for the pad carried by theholder.

7. In a polishing device, a stock, a pneumatic cushion carried by saidstock, a pump mounted on the stoclrfor intiating said cushion, said pumpcomprising a tubular pump barrel and reciprocative plunger, and saidbarrel extending completely through the pneumatic cushion and having anair release valve for effecting deflation of the cushion.

8. In a polishing device, a stock or holder, a pneumatic cushion carriedthereby, a cover assembled over said cushion, a. pump barrel, withreciprocating plunger detachably mounted upon the stock, an-air releasevalve-for deflating the cushion and means for controlling said valve,said valve controlling ,means also functioning means for fixing the pumpwith cushion in posi-.

tion upon the stock or holder.
